FRlCTlON-CLUTCH.-

Specification of Letters Patent.

Patented J my 24, 1906.

Application filed June 14, 1905. Serial No- 265,161.

To all whom it may concern.-

Be it known that I, AUGUSTUS FREDERICK MACK, of Brooklyn, Kings county, New York, have invented a new and useful Improvement in Friction-Clutches, of which the following is a specification.

The invention relates to a clutch mechanism wherein the parts operate by direct frictional contact and it consists in the construction hereinafter set forth, whereby the motion of a driving-shaft may be imparted at will to either of two driven shafts, both of said driven shafts being rotated in the same direction.

In the accompanying drawin s, Figure 1 is a side elevation of my improve clutch. Fig. 2 is a longitudinal section thereof. Fig. 3 is a detailed view in section, showiny the ring 5 in engagement and the ring 4 disengaged. Fig. 4 is a similar view showing both rings 4 and 5 out of engagement.

Similar characters of reference indicate like parts.

1 represents a rotary shaft, fast upon which is the disk 2, provided on one facewith a frustoconical flange 3 and With a central guideopening 8. The inner and outer peripheries of flange 3 furnish friction-surfaces for the rims of the inner and outer clutch-rings 4 and 5. The inner ring 4 is securedupon a shaft 6, while the outer ring 5 is secured to a sleeve 7, which surrounds said shaft 6. Roller-bearings 11 and ball-bearings 12 permit the sleeve 7 to rotate freely around the shaft 6, while relative motion lengthwise is prevented by the collars 13. 10 is an operatin -lever connected by yoke 14 to sleeve 7. hen said lever is swung on its pivot, it moves the sleeve 7 and the inclosed shaft 6 simultaneously in a longitudinal direction to bring the inner periphery of clutch-ring 5 and the outer periphery of clutchring 4 into or out of frictional contact with the flange 3. Thus when said lever is moved to the position indicated by dotted lines A in Fig. 1 the position of the clutch-rings is as shown in Fig. 2, the ring 4 being in frictional engagement with the inner periphery of the flange 3 and the ring 5 being out of engagement with the outer periphery of said flange. When the lever is brought to the position shown in full lines in Fig. 1, the clutch-ring 5 comes into engagement with the flange 3 and the c1utch-ring 4 is moved out of engagement with said flange, as shownin Fig. 3. When said lever is placed in its middle position, (represented in dotted lines at B, Fig. 1,) then both clutch-rings are moved out of engagement with the flange 3, as shown in Fig. 4. The shaft 6 has a prolongation 15, which enters the guide-opening 8 in disk 2. In this way the clutch-rin s 4 and 5 are guided in a right line during t eir movement into and out of engagement. It will be obvious that by this construction I may cause motion to be transmitted from the disk 2 to either the clutch-ring 5 or the clutchrin 4 at will, or, by placing the lever in its mi dle position B, I may wholly interrupt the transmission of motion from the disk 2, said disk then revolving freely upon the shaft 6. These capacities of the clutch I may utilize in any desired way, as by having a certain mechanism' driven by the shaft 6 and another mechanism driven from the sleeve 7 by means, for'example, of a gear-Wheel such as is shown at 21. It will also be observed that when one clutch-ring, as 4, is brought into engagement with the flange 3 the other clutchring 5 is at the same time moved out of engagement with said flange 3, and this capacity I may also utilize in connection with any suitable mechanism or mechanisms.

In another application for Letters Patent, Serial No. 245,991, filed February 17, 1905, I

have shown my present clutch in connection with transmitting-gearing for providing variable-speed transmission, in which construction I utilize in one specific way the capacities of my aforesaid clutch, as hereinbefore pointed out.

I claim 1. In a friction clutch mechanism, a driving-shaft, a fixed frusto-conical clutch-rin thereon, a driven shaft, a sleeve on sai driven shaft and two frusto-conical clutchrings respectively fixed on said sleeve and shaft and both rotated in the same direction by said first-named clutch-ring; one of said rings being surrounded by and the other surrounding said driving clutch-ring, and means for moving either of said driven rings into frictional contact with said driving-ring.

2. In a friction clutclg mechanism, adriving-shaft, a frusto-conical clutch-ring thereon, a longitudinally-movable driven shaft, a sleeve rotatable on said driven shaft, two frusto-conical clutch-rings respectively fixed on said sleeve and said driven shaft, one of said rings being surrounded by and the other surrounding said driving clutch-ring, and

means for moving said driven shaft to carry either of said driven rings into frictional contact With said driving-ring.

3. The combination of a driving-shaft, a disk thereon havin a central guide-recess, a

frusto-conical clutc ring on said disk, a longitudinally-movable driven shaft having one end entering and guided by said recess, a sleeve on said driven shaft and two frustoconical clutch-rings respectively mounted on said sleeve and shaft; one of said rings being surrounded by and the other surrounding said driving clutch-ring, and either of said rings being movable into frictional engagement With said driving-rin by the longitudinal displacement of said lriven shaft.

In testimony whereof I have hereunto set my hand in the presence of the two subscribing Witnesses.

AUGUSTUS FREDERICK MACK.
